The logo should feel fresh, insightful and modern. Kind of tech company-ish, though we're not a full on tech/web 2.0 company, we do use technology to deliver value to our clients. Really need to demonstrate that our company strikes the right balance between art and science when delivering our business solutions.
the logo should minimize the conflict inherent in the word 'versus' and try to highlight striking a balance between art and science.
The logo should be scalable to fit on printed marketing materials, websites and business cards.
Some thoughts on the logo could be the use of negative space, I always thought the Fedex logo was clever. Alternatively, some typography could be done with different combinations of capitalizations, such as artVScience, ArtVScience, artVscience, etc. Using a lower case 'a' for better feng shui but its not mandatory. An image/design can be used but it should be clever and subtle.
